WHEEL FOR PLANTERS.

Specification of Letters Patent.

Patented Jan. 9, 1906.

To all whom it may concern:

Be it known that I, GEORGE C. AVERY, a citizen of the United States, residing at I iouis ville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in \Vheels for Planters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in planters, and particularly to wheels therefor.

The object of the invention is the improvement of the structure of the sections or parts ofthe ground-wheel of a planter.

I/Vith this and other objects in view the invention consists of certain other novel constructions, combinations, and arrangements of parts, as will be hereinafter fully described, illustrated in the accompanying drawings, and more particularly pointed out in the claims hereto appended.

In the drawings, Figure 1 is a view in side elevation of a seedplanter to which is applied a ground or drive wheel made according to my invention. Fig. 2 is a view in front elevation of my improved wheel. Fig. 3 is a transverse vertical sectional view of the wheel, and Fig. 4 is a perspective view of the axle and one of the concavo-convexed disks or sections positioned thereon.

Referring to the drawings by numerals, 1 designates my improved wheel, employing an axle 2 in the construction thereof. In constructing a planter the axle 2 is journaled in boxes 3. A pitman 4 is connected at one end to crank-arm 5 and at its opposite end to a crank-arm 6, carried by hopper 7 of the planter. The crank-arm 5 is preferably integral with the axle 2.

The wheel 1 comprises, preferably, two disks or sections 7 and 8. These sections are similarly constructed, and therefore it will only be necessary to specifically describe one of the same. Each section is disk-shaped or concavoconvexed in structure. The section is provided with radial corrugations. A central aperture or opening is formed in the section within which the axle 2 is positioned. A notch or cut-out portion 9 is formed in each section or disk contiguous to the central opening. A lug 10 is positioned within the notch or cut-out portion 9 of one of the sections or disks when the axle is in its normal position within the sections, Figs. 2 and 3. This lug performs the function of a key for securing one of the sections and axle 2 against independent rotary movement. In the present instance section 7 is engaged by the lug 10, while the section 8 is normally retained against rotary movement with relation to section 7 and axle 2 by means of the corrugated edges of the sections interlocking, as will be clearly seen upon referring to Fig. 2. For securely retaining the sections upon the axle I preferably form an aperture 11 in the axle 2 and position within the aperture 11 a cotter-pin 12. It is to be noted that I preferably employ two locking means for securing the sections and axle 2 against independent rotary movement-to wit, the lug 1O (constituting axle fastening or locking means for one of the sections) and the corrugated interlocking edges of the sections, which constitute edge or peripheral locking means. Because of the similar structure of each corrugated section or disk it is immaterial which is first positioned upon the axle 2, as the opening and notch 9 are of such structure as to accommodate the axle 2 and the lug 10.

i The sections or disks when placed together assume a concentric position, and they will maintain this position as long as they .are held together by the axle. The corrugations of the sections or disks give the wheel more tractive force. A wheel constructed of uncorrugated sections often slips on the earth and the movement of the planter mechanism is then-not regular, while with a corrugated sectional wheel the liability of the Wheel slipping or an irregular movement of the mechanism is practically obviated. It will therefore be apparent that the wheel is of a hollow structure and that the sides of the hollow wheel are corrugated, thereby producing a roughened outer surface. While each section of the wheel is concavo-convexed, the sides of a complete wheel are bulged outwardly or are convexed.

That I claim is 1. A ground-wheel for planters, comprising a pair of radially-corrugated, interlocking sections, and means for securing said sections together.

2.. A ground-wheel for planters, comprising interlocking, radialbr-corrugated sections, an axle extending through said sections,

means for fixedly securing said sections and axle against independent, rotary movement, and means for securing said sections upon said axle.

3. 'A wheel for planters, comprising a pair of interlocking, concavo-convexed, radiallycorrugated sections, and an axle extending through said sections.

4. A wheel for planters, comprising a pair of sections or disks, each section provided with a corrugated edge, and an axle connecting said sections.

5. A wheel, comprising an axle provided with a lug, a pair of sections carried by said axle, one of said sections rovided with a notch, said lug secured within said notch, the lug and notch constituting means for preventing, independent, rotary movement of said notched section and axle, and interlocking means formed upon the edges of said sections and adapted to prevent, independent rotary movement of the same.

6. A wheel, comprising concavo-convexed sections, each section provided with a corrugated edge, the edges of said sections interlocking, thereby preventing independent movement of said sections, an axle extending through said sections, and means formed upon said axle and one of said sections and being capable of preventing independent, rotary movement of said axle and section.

7. A wheel, comprising dished sections, the sections in engagement at their outer edge, locking means formed upon the engaging faces of said sections and being capable of preventing independent movement thereof, a transverse member connecting said sections, and locking means formed upon said member and one of said sections and adapted to prevent independent, rotary movement of said section and member.

8. A wheel, comprising an axle, sections carried by said axle, the sections in engagement at their outer edge, locking means formed upon the engaging portions of said sections, and locking means formed upon said axle and one of said sections.

9. A wheel, comprising sections, the sections engaging at their outer edges, locking means formed upon the engaging portions of said sections, each section provided with a central aperture and a notch, an axle extending through the apertured portions of said sections, and a lug formed upon said axle an secured Within the notch of one of the sections.

10. A wheel, comprising sections, corrugations formed upon each of said sections, an axle engaging said sections, and means for fixedly securing said sections to said axle.

11. A ground-wheel for planters, comprising dished or concavo-convexed sections, said sections in engagement at their outer edge, a corrugation formed upon each of said sections, an axle engaging said sections, and means for fixedly securing said sections to said axle.

12. A wheel, comprising concavo convexed sections, said wheel provided with a roughened periphery, and means for locking said sections against independent, rotary movement.

13. A Wheel, for planters, comprising a hollow body provided with outwardly-bulged or convexed sides, and radial corrugations formed upon one of said sides.

14. A Wheel for planters, comprisin a hollow body provided with outwardly-bu ged or convexed corrugated sides.

15. A wheel for planters, comprising a hollow body provided with outwardly-bulged or convexed sides, and a roughened surface formed upon said body.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE C. AVERY.
